Goggles

ABSTRACT

Goggles include a goggle frame, a goggle lens to be detachably fitted in a groove formed on the inner peripheral portion of the goggle frame. The front and rear walls constituting the groove have ventilating openings opposing each other. Either a goggle lens which covers the opening of the rear wall or a goggle lens which allows the openings of the front and rear wall to communicate each other can be fitted in the groove.

FIELD OF THE INVENTION

[0001] The present invention relates to goggles, and more particularlyto goggles used for skiing and snowboarding

PRIOR ART

[0002] This type of goggles usually has a ventilation section to preventinner surfaces of goggle lenses from becoming clouded up with a skier'sbody temperature, sweating or the like, which allows to avoid accidentsdue to poor visibility during sliding.

[0003] This ventilation section, for example, has a construction inwhich air is let to be in through holes provided above goggles lensesfitted in a goggle frame. This type of goggles has the followingdrawbacks; first of all, providing a ventilation section narrows thefield of the vision by that size. Secondly, anti-fog effect is enhancedin slow and middle-slow sliding such as skiing, however, in case theyare used under a high speed such as in a downhill race and a jumpingrace, a large amount of air enters at a high speed from the holesprovided above the goggle lenses and this causes problems such ashurting the eyes of a wearer.

[0004] Therefore, skiers and the like have desired improvement ofgoggles in which a wide field of vision can be guaranteed withoutenlarging goggle frames and the amount of air-flow from ventilationsections can be easily controlled.

SUMMARY OF THE INVENTION

[0005] It is, therefore, an object of the present invention to providegoggles in which a wide field of vision can be guaranteed withoutenlarging goggle frames and the amount of air-flow from ventilationsections can be easily controlled.

[0006] Goggles according to the present invention include a goggle frameand a goggle lens detachably fitted into a groove formed on the innerperipheral portion of the goggle frame. The groove of the goggle frameis constituted with a front wall and a rear wall, and the walls areprovided with respective ventilation openings which are opposing to eachother. The goggles can include either a goggle lens which closes theopening on the rear wall or a goggle lens which allows the openings onthe front and rear walls to communicate each other.

[0007] The goggle lens which allows the openings on the front and rearwalls to communicate in the goggles according to the present inventionmay have cuttings at the portions corresponding to the openings.

[0008] Goggles according to the present invention may further beprepared for with plural goggle lenses having cuttings in varying sizes,so that changing lenses to be fitted in the groove of the goggle frameallows the amount of air-flow into inside of the goggle lens to bechanged.

[0009] The opening on the front wall in the goggles according to thepresent invention may be formed with plural gratings or alternativelycovered with a filter.

[0010] The embodiments of goggles of the invention stated above will bedescribed below with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

[0019]FIG. 1 is a perspective view of skiing goggles G. FIG. 2 is afront view of a goggle frame 1 of the goggles G. As shown in FIGS. 1 and2, the goggles G include a goggle frame 1, arms 2 provided on the rightand left end portions of the goggles frame 1, an expandable, elasticband 3 coupled to the goggle frame 1, and a goggle lens 4 detachablyfitted into the goggle frame 1.

[0020] The goggle frame 1 is made of soft material such as an elasticsynthetic resin, rubber or the like. As shown in FIGS. 1, 3 and 7, thegoggle frame 1 includes a lens fitting edge 1 a, a face abutment section1 b and a peripheral wall section 1 c connecting the lens fitting edge 1a to the face abutment section 1 b. The goggle lens 4 is detachablyfitted into the lens fitting edge 1 a.

[0021] As shown in FIG. 6, the lens fitting edge 1 a is provided with agroove 10 in which an outer peripheral edge of the goggle lens 4 isreceived. The groove 10 is constituted with a front wall 11 and a rearwall 12 (FIGS. 7 and 8) in which ventilation openings 13 and 14 arerespectively provided. In this embodiment, as shown in FIGS. 2 and 7,the opening 13 of the front wall 11 is formed in a oval shape in a frontview and provided with vertical gratings. The opening 14 of the rearwall is formed by cutting. In the groove 10, as shown in FIG. 2, isprovided with protrusions 15 and 16 for positioning the goggle lens 4and preventing removal of it.

[0022] The face abutment section 1 b, as shown in FIGS. 1 and 3, isprovided with a close contact material 17 such as sponge or monte planein order to give comfortable close fitting to a wearer's face.

[0023] The peripheral wall section 1 c, as shown in FIGS. 1 to 3, isprovided with ventilation sections 18 and 19 formed with plural holes onthe upper and lower constitutional walls. The ventilation sections 18and 19 are respectively designed to be closed by and covered with thinsponge plates S1 and S2. The reason for closing and covering theventilation sections 18 and 19 by the sponge plates S1 and S2 is toprevent snow and/or dust other than air from entering inside of thegoggles.

[0024] The arms 2 are formed with the goggle frame 1 in one body. Asshown in FIGS. 2 to 4, the arms 2 are shaped matching with the shape ofthe right and left end portions of the front face of the lens fittingedge 1 a. One end 20 of each arm 2 extends outwardly from the front faceof the upper portion of the frame of the lens fitting edge 1 a and theother end 21 thereof extends outwardly from the front face of the lowerportion of the frame of the lens fitting edge 1 a. The arms 2 in anon-used state extend substantially along with the front face of theupper and lower portions of the frame of the lens fitting edge 1 a. Asseen from FIG. 2, the arms 2 do not stand within the goggle frame 1 in afront view. The arms 2 have positions to receive the expandable, elasticbelt 3 at their free ends. More concretely, as shown in FIGS. 2 and 3,the expandable, elastic band 3 is attached to the each arm 2 in afashion that the end portion of the band 3, forming a cylindrical shape,surrounds a bar 22. The expandable, elastic band 3 includes band bodies30 and 30 which are made elastic. They are attached to respective arms 2and designed to be coupled together by means of a buckle 31.

[0025] The goggle lens 4 is made of synthetic resin plate (cellulousepropionate, triacetate, polycarbonate and the like) and has a highanti-scratch property and prevents ultra violet rays. And the insidesurface of the lens is provided with an anti-fog treatment.

[0026] For the goggles G in this embodiment, a goggle lens 4 a for acompetition, shown with the thick line in FIG. 5, and a goggle lens 4 bfor general use, shown with the think line in FIG. 6, are prepared.

[0027] The thick line in FIG. 5 shows the outline of the goggle lens 4 afor a competition. In a state where the lens 4 b is fitted in the groove10 of the lens fitting edge 1 a, as shown in FIGS. 5 and 7, the opening14 of the rear wall 12 is covered.

[0028] The thick line in FIG. 6 shows the outline of the goggle lens 4 bfor general use. The lens 4 b has cuttings 40 at the positionscorresponding to the openings 13 and 14. Therefore, in the state wherethe lens 4 b is fitted in the groove 10 of the lens fitting edge 1 a, asshown in FIGS. 6 and 8, the openings 13 and 14 of the front and rearwalls 11, 12 is communicating each other through the cuttings 40.

[0029] The goggle lenses 4 a and 4 b, as shown in FIGS. 5 and 6,respectively have recesses 41 and 42 matching with the foregoingprotrusions 15 and 16. The stopping force between the protrusions 15 and16 and the recesses 41 and 42 reliably fixes the goggle lens 4 a or 4 bat the certain position of the goggle frame 1.

[0030] When the goggle lens 4 a for a competition is set to the goggle,as stated above, the opening 14 of the rear wall 12 is covered by thegoggle lens 4 a and the amount of air-flow into inside of the gogglelens 41 lessens so that the influence of wind against the eyes of awearer can be alleviated.

[0031] When the goggle lens 4 b for general use is set to the goggle, asstated above, the openings 13 and 14 of the front and rear walls 11 and12 are communicating each other, and the amount of air-flow into insideof the goggle lens 4 b increases so that anti-fog effect is enhanced.

[0032] In the goggles of this embodiment, the ventilation section isformed on the goggle frame 1 per se, not a ventilation section is addedwithin the area of the goggle frame 1 which was described in the sectionof Prior Art. Therefore the field of vision is not narrowed.

[0033] The present invention should not be limited to the aboveembodiment. In addition to the goggle lenses 4 a and 4 b, a goggle lens4 which has smaller cuttings than those of the goggle lens 4 b may beprepared for the goggle. When this goggle lens 4 is set to the goggleframe 1, the amount of air-flow into inside of the goggle lens 4 can becontrolled in a middle degree between those of the goggle lenses 4 a and4 b. Therefore, provision of goggle lenses with cuttings in varyingsizes allows to control the amount of air-flow into inside of the gogglelenses.

[0034] The opening 13 in the above embodiment may be covered with andclosed by a sponge plate as filter. Furthermore, the shape and size ofthe openings 13 of the front wall 11 and those of the openings 14 of therear wall 12 can be freely determined.

[0035] The goggles of the present invention are not limited to skigoggles, but can be applied to goggles for other purposes, such asdust-protective goggles, goggles used for cold weather districts.

[0036] With the construction stated above, the present invention canprovide goggles in which the wide field of vision can be guaranteedwithout enlarging the goggle frame and the amount of air-flow from theventilation sections can be easily controlled.
